High-Efficiency Pesticide Spraying Machine

This machine is designed for efficient agricultural pesticide liquid application over large areas, providing broad coverage, adjustable spray patterns and precise control for orchards, fields and plantations.

Typical spray height is 2–5 meters and spray width per fan is 6–10 meters. Overall working width is stated as 14–20 meters depending on configuration and nozzle setup.

The unit is driven by a tractor power take-off; recommended supporting power is tractors over 40 hp.

It uses a triple (3-cylinder) plunger pump with flow about 100–120 L/min. Pump pressure is specified up to 0–4 MPa in some references; typical operating work pressure range is 0.3–2.5 MPa for normal spraying.

Standard medicine (chemical) tank capacity is 3000 L. Stirring uses return-water stirring plus negative-pressure mixed-flow stirring. Filtration is a tertiary filtration system to protect nozzles from clogging.

The machine has a large fan (800–1000 mm diameter depending on model) with variable-speed capability (e.g., 1800 rpm listed) and uses three-in-one precision nozzles. Nozzles are adjustable and multiple-nozzle design improves droplet fineness and uniform coverage.

Spray control is sectional with independent switches, allowing you to open/close fan/nozzle groups for precise, zone-specific application. A PLC is included for reliable control and automation of operations.

Weight is approximately 324.2 kg. Two sets of dimensions are referenced in product materials: a compact listing (likely chassis dimensions) of roughly 1360 x 1200 x 1300 mm and a full mounted machine dimension of 4200 x 1720 x 1910 mm. Final size depends on configuration—confirm the exact model dimensions with the supplier before purchase.

The gearbox is described as autonomous (independently designed), which generally simplifies maintenance and improves durability; follow the gearbox service schedule in the operator manual for lubrication and inspection intervals.

It uses heavy-duty widened vacuum rubber tires that are slip- and wear-resistant, providing good stability and traction during field operations.

Operators should use appropriate personal protective equipment (PPE), keep bystanders away from spraying, follow chemical label directions, ensure proper pressure and nozzle selection, shut off sections when turning or transporting, and perform pre-operation checks of hoses, filters and seals.

Regularly rinse the tank and circulation lines after each use, remove and inspect nozzles for wear or clogging, clean filters and strainers (tertiary filtration stages) frequently, and replace worn nozzles to maintain droplet size uniformity and correct flow rates.

Yes—the product is available under Brand Geetien and OEM configurations. Contact the manufacturer or authorized dealer to discuss customization options (tank size, fan diameter, nozzle packages, control systems) and lead times.

Common spare parts include nozzles, filters, pump seals, hoses and gearbox components. Ask your supplier about spare parts kits, recommended service intervals, local service centers and warranty coverage when ordering.

Select nozzle type and size based on desired droplet size, application rate and crop/target pest. Use the machine's pressure range (recommended 0.3–2.5 MPa for normal spraying) and pump flow to match the nozzle manufacturer's charts. For best results, consult the nozzle chart and perform field tests at various pressures.
